MILKI'NG DEVICE Henry L. Morency, Boulder, 0010. Application July 26,1933, Serial na'caaeie -2 Claims. I (01. 31-450) This invention relatesto improvements in milking devices and pertains particularly to animproved milking can and means for facilitating the conduction of milkdirectly from the teat of 5 an animal thereinto.

The primary objectof the present invention is to provide an improvedmilking device wherein the possibility of contaminating the milk as itis being withdrawn and discharged into the receptacle, is positivelyeliminated. 1

In the milking of a cow 'even under the most sanitary conditions theentrance of some foreign matter into the milking receptacle cannot beprevented and in cases where the milker is not particularly careful orthe conditions under which the milking is conducted are insanitary, themilk receives a large amount of bacteria from various sources. g g 1 IBy the use of the device embodying the present invention the milk is notexposed at any time between its passage from the teat of the animal intothe receiving receptacle and the entrance of bacteria into the milk'fromthe hands of the milker orfrom other sources is positively prevented. r

A further object of the invention isto provide a milking deviceconsisting of a milk receiving receptacle and a flexible tube connectedat one end 30 with the receptacle? and adapted to connect at its otherend with the teat of the cow, in which a novel means is employed forcoupling the tube with the receptacle whereby the coupling operation orthe uncoupling of the tube from the receptacle, may be performed quicklyand easily.

Another object of the invention is to provide a receptacle having acover so designed that the milk conducting tube will connect therewithin such a manner that it will lead straight from the animal to thereceptacle without being bent or otherwise deformed in any way whichwould interfere with the free fiow of the milk therethrough.

g A still further object of the invention is to provide, in a device ofthe character described, a receptacle having means therein whereby themilk may be easily agitated during the milking process so as tofacilitate the rapid cooling there of.

The invention will be best understood from a consideration of thefollowing detailed description taken in connection with the accompanyingdrawing forming part of this specification, with the understanding,however, that the invention is not confined to any strict conformitywiththe showing of the drawing but may be changed or modified so long assuch changes or modifications mark no material departure from thesalientfeatures. of the invention as expressed in the ap- .5 pended claims.

In the drawingz Figure 1 is a View of the milk receptacle partly in sideelevation and partly in vertical section showing in elevation a portionof the agitating means therein;

Figure 2 is a view in section of the receptacle taken on the line 22 ofFigure 1; i Figure'3 is a view in side elevation of the recepr tacle lidviewing the same at right angles to the plane in which the same is shownin Figure *1;

Figure 4 is a view partly in side elevation and partly in longitudinalsection of one 01' a pair of tubes which form a part of the device andwhich are coupled with the receptacle lid.

Referring now more particularly 'to the drawing wherein like numerals ofreference indicate corresponding parts throughout the several views,

the milk receptacle exclusive of the lid therefor,

is indicated generally by the numeral I. This receptacle has a reducedthroat or neck portion which is in the form of a vertical fiange 2.'Suitable eyes 3 are formed upon the shoulders of the receptacle withWhichthe ends of the. handle bail 4 are oscillatably connected, theintermediate portion'of the handle bail, in the illustration, be-

ing broken away. I

Within the receptacle there is mounted in vertical position ,upontheabottom thereof the. baflie wall 5 which extends through the. radialcenter of the receptacle and is provided with a series of openings 6,preferably three.

The lid of thernilk receptacle is indicated as a whole by the numeral 1,and as shown, com- 40 prises the top plate portion 8 which is in theform of a disk, from the under side of which depends the annular flange9 which is inset with respect to the edge of the plate 8 and is of theproper diameter to snugly fit into the collar or throat portion 2 of thereceptacle.

In order that the. lid 7 may be retainedfirmly in place the collarportion 2 of the receptacle has pressed therein the inwardly projectinglugs 10 which coact with the recesses I! pressed in the flange 9 of thelid, to lock the lid in place. 7

The portion 8 of the lid or cover has the up,- wardly pressed portioni2, one wall of which is disposed at a'slightinclination with respect tothe surface of the portion 8 of the lid, as indicated at [3. Thisinclined face [3 is directed toward the adjacent edge of the lid and isprovided with a pair of openings each of which is indicated by thenumeral I l. The lid is also provided with a handle l5 by which itsapplication to and removal from the receptacle is facilitated.

The numeral I6 indicates generally the tubes which are connected withthe lid of the receptacle.

Thesev tubes are formed throughout of rubber and as illustrated they areof gradually decreasing diameter from one end to the other. One of thetubes is of slightly greater length than the other to compensate for thedifferences in the distance between the receptacle and the two teatswith which the tubes are connected.

The larger ends of the tubes, which are indicated by the numerals H, aredesigned to be slippedover the animals teat and'these ends areprovidedwith relatively heavy surrounding flanges l8- against which the thumband fore finger of the operators hand positions in the use of thedevice.

The larger ends I! of the tubes are also formed relatively thin so thatthey can be readily adjusted as necessary to snugly receive the teatfofthe animal and at the same time the hand of the operator can work theteat in the required manner without interference from the tube which isinterposed between his hand and the teat.

The rubber bodies of the tubes gradually increase in' thickness from apoint substantially midway of theirends to the smaller ends thereofand-these thicker portions of the tubes are semirigid. At the smallerends each of the tubes is designed to he slipped into an opening M inthe receptacle cover and in addition to being tapered to facilitatethis, is provided witha surrounding rib l9 and a relativelywidelsurrounding flange 20 which lies over and against the adjacent rib19 in the manner illustrated. From this it will be readily apparent thatwhen the tapered end of either tube is inserted'into an opening M therib portion 19 'may be. forced through the opening but the adjacentflange 28 will stop the further insertion of the tube so that the edgeof the opening will locate between the rib and the flange and thus forma' tight joint which will prevent theientrance of any foreign-matterinto the'receptacle. v v

In additionto being made of good quality rubber the interior of thetubes are finished to form a smooth surface so that no places will befound in which bacteria may lodge. This also facilitates the readysterilization and cleaning of the tube. In the use of the device thetubes are connected with the lid of the receptacle in the mannerdescribed and the larger ends of the tubes are slipped over the teat ofthe animal so that the milk as it flows from the teat will pass throughthe tubes directly into the receptacle and will not 'be exposed to thesurrounding outside atmosphere.

During the milking operation the contents of the receptacle can be keptagitated so that the same will more rapidly cool off, by the operatoroccasionally partially rotating the receptacle back and forth upon itsvertical or longitudinal axis so as to causethe milk in the can to beagitated, thus effecting the more rapid cooling by the action induced bythebafile wall.

Having thus described the invention, what is "claimed is:'

1. In a milking receptacle, a receptacle body having an open top, acover for said open top, said cover having a portion of its top pressedupwardly to form a flat inclined wall, said wall having an aperturetherein, and an elongated milking tube of resilient material having oneend of smaller diameter than the other, a broad flange surrounding saidtube adjacent the smaller end, a rib surroundingthe tube in closeproximity to the flange and between the same and the adjacent end, andsaid tube being tapered from said rib to the adjacent end to facilitateits introduction into said inclined wall opening, said rib beingyielding to pass through the opening whereby the edge of theopening willbe held between the rib and said flange.

2. In a milking receptacle having a wall pro vided with an aperture, 9;tube of resilient material of constantly decreasing diameter from oneend to the other, a relatively broad flange surrounding the tubeadjacent the end of smallest diameter, a rib surrounding the tube inabutting relation with said flange and between the same and the adjacentend of the tube, the said tube having its outer face tapering from saidrib to the adjacent end, the tube being of constantly decreasing wallthickness from said flange toward the end of greatest width, and aflange of relatively heavy material secured to and surrounding the tubeat the end of greatest diameter, said tapered end of the tube beinginsertible in the receptacle wall opening and said rib being adapted topass through the opening to engage the edge ofthe same between the riband the first mentioned flange.
